Paint and varnish remover.



UNITED STATES PATENT OFFICE.

LEO ORNSTEIN, OF BROOKLYN, NEW YORK.

PAINT AND VARNISI-I REMOVER.

T 0 all whom it may concern:

Be it knovm that I, LEO ORNSTEIN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Paint and VarnishRemovers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to that class of paint and varnish removers inwhich ether, alcohol, acetone, benzol, carbon bisulfid or a similarsolvent are employed but I have discovered that by the addition ofcertain ingredients not hitherto employed in paint and varnish removersthat the work of removing paint and varnish is materially assisted in aneconomical manner.

The composition I have found most eflicacious in removing paint andvarnish is a mixture of ether, alcohol and anilin oil. This mixture willwork satisfactorily in various proportions but I have found thefollowing composition of especial efficacy. I take of ether 10% byvolume, of alcohol, either methyl or ethyl, by volume and of anilin oil35% by volume. Pure anilin chemically known as C- I I VI-I may beemployed in the manufacture of my paint remover but commercial anilinoil containing some toluidin as an impurity will be found equallyellicacious. In fact toluidin acts similarly to anilin when mixed withether and alcohol or other solvents for use as a paint remover andtoluidin may be substituted for anilin where commerical reasons makethis desirable.

A composition made according to the above formula is efficacious as aaint remover very largely on account of t e anilin contained therein.Ether, alcohol, bisulfid of carbon, light tar oils and other volatilesolvents while having a solvent action on paints and varnishes may notbe used alone on account of their volatility and I have found thecombination of anilin with one or more of these to be eflicient for thereason that anilin is not volatile, combines readily Specification ofLetters Patent.

2 with other solvents, prevents by its presence the toorapid'vaporization of other solvents and has itself a distinct solventaction on paint and varnish compositions.

In some cases it will be found desirable to use a thickener for my paintand varnish remover where the action of the solvents is slower onaccount of the thickness, hardness or age of the paint or varnishcoating. For the purpose of thickening my paint remover I employ a smallamount of wool fat or a particular variety of wool fat commerciallyknown as lanolin which is readily miscible or soluble in the otheringredients of my paint remover and which I have found eflicient as aretarding agent.

In practice I have found the following composition suitable for use as apaint and varnish remover: ether 10%, alcohol 55%, Wool fat 5% andanilin 30%, all the ingredients being stated by volume.

What I claim is:

1. In a paint and varnish remover, the combination of ether, alcohol,anilin, and a retarding agent.

2. In a paint and varnish remover, the combination of anilin, ether,alcohol and wool fat.

3. In a paint and varnish remover, the combination of anilin, ethylalcohol, ether and wool fat.

4. In a paint and varnish remover, the combination of anilin, alcohol,ether and lanolin.

5. In a paint and varnish remover, the combination of anilin, ether,ethyl alcohol and lanolin.

6. In a paint and varnish remover, the

wool fat 5% and anilin 30%, all the ingredients being stated by volume.

7. In a paint and varnish remover, the combination of ether, alcohol,anilin and toluidin.

In testimony whereof I affix my signature in presence of two witnesses.
